...you already can earn most of the items, and there's only two units (that are hardly used anyway) that have to be "purchased". Once you unlock them, everyone you face will have them. That could be more of a disadvantage than an advantage, considering how you look at it...
I don't mind that there's "elite" and "premium" memberships, since they don't give any in-game benefits. It's just customization, so I don't see why anyone has a problem with that part. I just wish we had access to all the maps normally...
There's such a thing as TOO MUCH customization. Remove/combine some of the stats and perhaps allow the upgrading of a unit from one type to the next rather than having 20 unit types.
